UNITED sTATE$ EDwAnnTHoMAs JONES, or NEW'ORLEANS, Louisiana RADIOCONTROLLING Dnvron.

To all wlwm t may concem Be'` ityknown that I, EDWARD' THOMAS l JoNns, acitiz'en of the United States., residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful-Improvements in-Radiocon-y L0 for controllind radio circuits es eciall in to the receivinf ai )aratus' forming an" air c 9 i is 7 is trolling '-Devices, of-which the following is a specifica-tion;

.`My invention relatesv to a switch-ing device yregardsto the transfer of-'the antenna from receiving to transmitting position, orf-vice versa; 'A

One 'object of this invention is to provide a `switch having high insulatingfqualities confined' to the .switch member supports,

' 4thereby lessening the chancefor leakage and reducing the manufacturing costs.

A. furtherl object is to provide a switch which can be :changed from one position to another in the'least vpossible time, .thereby adding materially to its advantages over the present types l'employed.

still further object'of this invention is to provide a radio controlling device in the form of aswitchv with. movable contact members taking up considerably less table space than is required hy similar instruments on the present-day market. This is 'of course .a very practical and saving feature. Cheapness of construction due to the `few essential pieces or members plays an impor tant part in addition to the featuresalready claimed for this device. l'

My invention will be more clearly underhr i, ,stood vby refe-rence to 4the accompanying -ceives 1`w-hen the same -is brought in a downward position; 3 represents a spring contacting member which 'is forced apartfrom 2 by 1 when the latter is in a downward position. 4 and'5 are switch members which v serve to open the primary power supply at the right moment, for instance, 'when reeeiving; so that transmitting cannot be ef 'fected f This protects the receiving apparatus and also the operator.

is down and betweenl the jaws of 2)'i is.

forced awayfrom 2 upon 1 bearing down' on 6 which is ya' small' insulatingubushing lor stud., This is merely to disconnect the metal lic circuits of the transmitter from the antenna and receiver proper. It is only necessary to have the circuit between and'i opened slightly, in facty the gap may be -femployed to advantage as an added, protection gap f or high potential 'l surges which may7V .strike the antenna while receiving',l such as a bolt of lightning.

,receiving inductance which offers consider-I able opposition-to such surges. l Posts orsupports, 7, 8 and 9 are composed vof bakelite and 'are made fast' to thebase 1() which can lbe of woochor 'even metal in -so far as the insulation of the base is concerned, for the'i'nsulation requirements of such a device are properly taken care of by thc The surges would trav-A erse the-small-air gap in preferenceI to the posts 7, 8, and 9. The switch members 1. 2.

and 3 are al1 supportedat the uppermost ends of the bakelite rods. 'In Vthese 'specifications I point out that bakelite is employed;

l bers and Just how the switch functions .in

these circuits.

That I claim is,

1. In a radio system the combination of a transmitting apparatus, an antenna system, va receiving apparat-us. means connecting the antenna to said ltransmitting apparatus.; means adapted to disconnectsaid connectingmeans, rnd establish connection between said antenna and said receiving apparatus, said first named means forming a protective gap 'across said `receiving apparatus when said receiving apparatus is connected with said antenna.

2. In a radio system the combination' of an antenna, a receiving apparat-us. a groun d-. 'ing circuit, means connecting the antenna with said receiving apparatus, means adapt ed to disconnect saidconnecting means and so.v

means associated witlrsaid grounding circuit forming a protective gap r." across said receiving apparatus when said receiving apparatus is connected with said antenna.

In a radio system the combination of a transmitting apparatus, an antenna system, a receiving apparatus, means connecting the antenna to said transmitting apparatus, means adapted to disconnect saidconnecting means, and establish connection between said antenna and said receiving apparatus, comprising a metallic pivoted blade, a knob for manuallyv yrotating said blade about its pivot, an electrical contact carried on one end oi' said blade but insulated therefrom, metallic connections ar 'anged to co-operate with saidv blade and contact, and a resilient member mechanically operative against said blade and adapted to form a protective gap across said receiving apparatus when said receiving apparatus is connected with said antenna.

4.In a radio system the combination of a transmitting apparatus, a source of power therefor, an antenna system, a receiving apparatus. means connecting the antenna to said transmitting apparatus, means connecting said source of -power to said transmitting apparatus, means adapted to disconnect said connecting means and establish connection between said antenna and-'said receiving apparatus, said first named means forming a protective ga'p across said receiving apparatus when said receiving apparatus is connected with said antenna.

-5. In a radio system the combination of a Vtransmitting apparatus, a source of power therefor, an antenna system, a receiving apparatus, an insulated support, a rotatable metallic blade pivotally mounted thereon and connected with said receiving appa- `atus, a knob for manually rotating said blade, an electrical contact carried on one end of said blade -but insulated therefrom, metallic clips arranged on opposite sides of said support and adapted to receive said blade and electrical contact respectively and a resilient member mechanically operative against said blade and adapted to open the circuit from said transmitting apparatus to said antenna and form a protective gap when said blade is rotated to connect said receiv l ing apparatus with said antenna.

6. In a radio system the combination of a transmitting apparat-us, an antenna system, a receiving apparatus, means connecting the antenna to said transmitting apparatus, means adapted to disconnect said connecting means, and establish connect-ion between said antenna and said receiving apparatus, comprising a' pivoted blade, 'an insulated vertical support at the pivot thereof, a horizontal base, a knob for rotating said blade about said pivot, contacts arranged within an angle ot' 18() degrees and below the plane of said pivot on opposite sides of said support, said blade andcontacts connecting respectively the transmitting and receiving apparatus with said antenna when said knob is rotated in opposite directions.
